Kraken, God of the Ocean

Indestructible.
If your devotion to Blue and Black is less than
seven, Kraken is not a creature.
At the begining of your upkeep, you may tap any number of basic lands you control. For each
island tapped this way, create a 1/2 Blue Octopus creature token. For each swamp tapped this way, target creature gets -1/-1 until the end of the turn.
